Sixteen queries, performed on the two systems, resulted in 247 unique relevant references from EMCS and 559 from TOXLINE. The overlap varied considerably, from 6 to 50 percent. It is remarkable that TOXLINE, with nine subfiles specially compiled for toxicology, can be supplemented by EMCS, which in the present study delivered 31 percent of all the…

Concentrates on the practical, everyday aspects of online search strategy, specifically offering ideas and comments on search strategies for STAIRS users. Included are tables listing the logical operators available on the system and the search level (document, paragraph, sentence, word) of each. (Author/JD)

Explains search commands for SERIDU, an online bibliographic search system developed at Brussels Free University. These commands and output formats are compared with Euronet commands (from which they were derived), with existing INFODOC storage system commands, and with the planned BIDULE system commands. An evaluation of SERIDU is included. (SW)

Discussion of online interactive search systems focuses on developments in the area over the past decade, the possibility of the end user undertaking online searching for him/herself, the changing role of the information scientist, implications for the information manager, and electronic publishing. Eight references are included. (EJS)

A course in basic information retrieval principles and use of online document retrieval systems is a curriculum requirement for undergraduate computer science students at Stockton State College in New Jersey. Contents of the course include both theory-oriented lectures and online search sessions using DIALOG. Eleven references are listed. (SW)

Compares features of selective dissemination of information service in information retrieval systems Quest and Orbit with those of smaller noncommercial system, George 3. Construction of profiles, editing during construction, and editing of stored profiles are noted. Examples of method of constructing and editing a profile in George 3 are…

This paper reviews the history of separate online system interfaces which led to efforts to develop expert systems for searching databases, particularly for end users, and introduces the research on such expert systems. Appended is a bibliography of sources on interfaces and expert systems for online retrieval. (Author/EJS)

The Drug-Interface, prototype system built to facilitate retrieval of drug related information, automatically connects to DIALOG Information Retrieval Service via available networks, aids user in formulating and/or revising search strategy, sends query to DIALOG, displays results of search, and downloads relevant pieces into Macintosh data file.…

Describes prototype system that provides retrieval from hierarchically structured full-text databases such as legal statutes and regulations and engineering standards. Enhanced retrieval is provided through integration of three different access techniques dependent on inherent hierarchical text structure: menu, Boolean combination of keywords,…

Presents typology of online search heuristics consisting of six main classes: philosophical attitudes and overall approach; language of problem description; record and file structure; concept formulation and reformulation; recall and precision; and cost efficiency. Heuristics in each of the six classes are listed and selected examples are briefly…
